State of AI breaks down enterprise AI adoption for 2026: Discrepancies across usage, spend, and financial returns

State of AI analyzed the divergent enterprise AI adoption metrics projected by major research and data organizations for 2026, pointing out that because denominators and definitions vary, there is no single adoption metric. A McKinsey survey showed that nearly 90% of surveyed organizations regularly use AI in at least one business function; Ramp transaction data revealed that 55.9% of its sampled businesses incurred AI-related spending; meanwhile, the U.S. Census Bureau's BTOS sample found that only 19.8% of businesses had used AI in the prior two weeks.
